Lamb of God (Greek: ἀμνὸς τοῦ θεοῦ, amnos tou theou; Latin: Agnus Dei) is a title for Jesus that appears in the Gospel of John. It appears at John 1:29, where John the Baptist sees Jesus and exclaims, "Behold the Lamb of God who takes away the sin of the world." As a visual motif the lamb has been most often represented since the Middle Ages as a standing haloed lamb with a foreleg cocked "holding" a pennant with a red cross on a white ground, though many other ways of representing it have been used.
